Abstract

The delicious fruit Litchi chinensis is a commercially important heterozygous cross-pollinated fruit species of the world. To increase its production of this fruit, plant breeding is required. Henceforth, the conservation of its germplasm resources is an important step toward improvement of new cultivars resistant to abiotic and biotic stresses through selection and breeding technologies. Two major approaches used for conservation of plant genetic resources are in situ and ex situ. Both approaches are important and complementary to each other for sustainable agriculture. It is challenging to conserve litchi germplasm through seed, field maintenance, and in vitro storage because of its recalcitrant nature and owing to various biotic and abiotic factors. Of all the various strategies of ex situ conservation of litchi, cryopreservation of litchi germplasm using its embryonic axis or pollens is a promising option for conservation of germplasm.
